1 Dr. S. Capaccioli Prof. F. Pegoraro Università di Pisa Scuola di Dottorato Galileo Galilei School of Graduate Studies Applied Physics GALILEIAN SEMINARS: "High Pressure Studies of Matter"

2 An ancestor of pressure experiments: Firenze (1667) Magalotti 1667, Saggi di naturali Esperienze One of the question of Accademia del Cimento: Can the volume of liquids be reduced by an external perturbation? Some experiments about the compression of water Maxim: >

3 Pressing on: The legacy of Percy W. Bridgman ( ) Paul McMillian, Nat.Mat , Nobel Prize for High Pressure Physics Max Pressure 10 5 bar=10 GPa Equation of state of materials, polymorphism, amorphization Isopropyl alcohol

4 2011: 65 th anniversary of Nobel Prize to Bridgman Is it high pressure an obsolete subject, ready for retirement? Not at all! In the last decades several improvements: - P up to some Megabar= GPa - dramatic changes in physical and chemical properties of matter, up to to the formation of new classes of materials.

5 -Modification of structure and bonding with compression, - pressure-induced phase transitions and polymorphism, - tuning of vibrational dynamics, -new states of electronic and magnetic order, - etc. High pressure Studies of Matter interesting for: Condensed Matter Physics Chemistry Astrophysics Geophysics Ichimura, Phys Rep 1995
